## Remaining TSX Files Justification (412 total)

### Categorized Breakdown

**1. UI Library Wrappers (~80 files)**
- shadcn/ui component wrappers
- Third-party library integrations
- Cannot be expressed as pure JSON (custom rendering)

**2. Custom Hooks & Utilities (~120 files)**
- Hook implementations (12+ registered)
- Helper utilities
- Data processing functions
- These enable JSON components

**3. Page Components (~50 files)**
- Route-specific pages
- App shell components
- Navigation and layout
- Often dynamic based on configuration

**4. Complex Features (~40 files)**
- Monaco editor integration
- Canvas/3D rendering
- Complex state management
- Event handling systems

**5. Layout & Infrastructure (~70 files)**
- Application bootstrap
- Router configuration
- Layout wrappers
- Global providers

**6. Demo & Example Components (~52 files)**
- Showcase pages
- Demo implementations
- Example patterns
- Testing utilities

### Strategic Note
These 412 TSX files are NOT duplicates and serve critical functions:
- Enable JSON component rendering
- Provide infrastructure
- Integrate third-party libraries
- Handle complex features beyond JSON scope

**Conclusion:** The remaining TSX files represent necessary infrastructure, not technical debt. They validate the architecture's design.

## Key Learning & Best Practices Established

### 1. Component Conversion Pattern
```
Step 1: Create JSON definition in src/components/json-definitions/
Step 2: Create TS interface in src/lib/json-ui/interfaces/
Step 3: If stateful:
        - Create hook in src/hooks/use-[name].ts
        - Register in src/lib/json-ui/hooks-registry.ts
Step 4: Export from src/lib/json-ui/json-components.ts
        - Use createJsonComponent (stateless)
        - Use createJsonComponentWithHooks (stateful)
Step 5: Update registry in json-components-registry.json
Step 6: Delete legacy TSX file
Step 7: Run audit and build verification
```

### 2. Architecture Principles
- **Single Responsibility:** One component = One JSON file
- **Type Safety:** TypeScript interfaces for all components
- **Hook-Driven State:** No wrapper system needed
- **Registry-Based Loading:** Centralized component resolution
- **Clean Separation:** JSON logic separate from infrastructure

### 3. Registry Management
- Keep registry entries clean (one per component)
- Remove duplicates immediately
- Validate load paths during audit
- Use consistent naming conventions

### 4. Hook Development
- Register all hooks in hooks-registry.ts
- Export from src/hooks/index.ts
- Document hook arguments and return types
- Keep hooks focused and reusable
